Aerial Mosquito Larvicide Applications

To
better protect our communities and the environment, the Vector Control
Program (VCP) applies mosquito larvicide via helicopter to mosquito
breeding areas that cannot be treated by hand. These aerial
applications occur every three to four weeks during the mosquito
breeding season, generally April to October, or as needed.

The granular larvicides used by the Vector Control Program act
specifically on mosquito larvae and will not harm people, pets,
plants, or wildlife. The larvicide consists of granules
containing Bacillus sphaericus,Bacillus thuringiensis
israelensis, and/or Saccharopolyspora
spinosa products. These naturally occurring bacteria
target mosquito larvae and prevent them from developing into biting adults.
